My vehicle "passed" the engine recall only to have the engine blow at 33,000 miles. My vehicle was at the dealership for 52 days most of the time was spent waiting for the new engine. Dealership was amazing, GMC however is the worst. My new engine has about 1,000 miles on it and it stutters occasionally when the auto start turns on.

On XXX around noon in medium traffic I was traveling on the [XXX] southbound at about 65 miles per hour when the engine suddenly stopped with no warning. To make matters worse the dash instructed me to apply the brake to start?? Not at 65 mph! I was able to coast onto the offramp safely and call for a tow to the GMC dealer in [XXX]. They diagnosed the failure to the engine seizing. I was fortunate to pull off the freeway as being an experienced driver for more than 50 years although it would be anyone's opinion that a less experienced driver could have been injured or worse. My fear is that the replacement engine that GM will install again have the same problem at any time in the future with no warning and I or my family will not be as fortunate the next time.

I have a 6.2L that we took in with bad rods due to the cam. The fixed the motor and now it is consuming oil and GM says it is normal. Normal for an engine to consume quarts of oil?? I cannot trade out of the vehicle because of the extreme depreciation that these vehicles have incurred due to the known engine issues. I know others are having the same issues I just want GM to make this right and help loyal customers.

Filing as a proactive data point for the ongoing NHTSA Office of Defects Investigation Engineering Analysis (EA26005) regarding GM 6.2L L87 engine failures. Vehicle is a 2026 GMC Yukon XL AT4 equipped with the 6.2L V8 and 10-speed transmission. The vehicle currently has approximately 2,800 miles and operates perfectly with no mechanical symptoms, ticking, or loss of propulsion. As an active preventive measure against internal component contamination, early engine oil changes were performed at 700 miles and 1,700 miles by a certified franchise dealer (Alpine Buick GMC). The engine continues to use the factory-specified 0W-20 oil viscosity. A magnetic oil drain plug has been installed to monitor for premature ferrous bearing and crankshaft debris at future service intervals. This report is submitted to ensure 2026 model year data running 0W-20 oil is officially documented within the federal investigation scope.

I know an engineering analysis has been opened on the 6.2L motor for GM models. I just want on the record that my wife has a 2022 GMC Denali XL that had the engine replaced in December 2025. After that motor replacement it repeated the same issue July 4th 2026 and the dealership replaced the engine a second time for the same reason, and I will be attaching each invoice for both replacements. Just want to have the #'s updated to show the remedy doesn't seem to work or in my case it didn't and I have seen numerous news articles talking about this.

ENGINE
While driving in passing lane on interstate highway at approximately 65 mph engine lost power. Dashboard warning "vehicle in neutral" message appeared. "Press start" message appeared. Tried to start the engine but did not start. Slight downhill while on highway and had to make it to right shoulder since no shoulder on left side of highway. Glided across 2 lanes to right lane and luckily an exit came up while still gliding slightly downhill. Exited ramp and got off highway to an empty parking lot. Put vehicle in Park. Since engine failed, power steering was normal as was all electrical components. Once stopped, vehicle was not able to be shifted into Neutral. Message " unable to shift to Neutral under conditions " appeared. Vehicle had to be towed with rear wheels on dollies since it was stuck in Park. Was very lucky to get vehicle across lanes of traffic and off highway to a safe location. Had vehicle towed to nearest GMC dealership where it was diagnosed as internal engine failure covered under recall for this particular engine. (6.2 liter).

ENGINE
I am reporting a severe, recurring, and life-threatening manufacturing defect involving a sudden, catastrophic loss of motive power at highway speeds on the interstate. This vehicle has suffered two identical valvetrain failures that placed my passengers and nearby motorists in extreme danger. Incident 1 (Approx. 40,000 miles): While traveling at high speed on the interstate, the vehicle violently shook, all engine warning lights flashed, and the engine suffered an immediate, near-total loss of propulsion. The vehicle was towed to an authorized GMC dealership, where technicians diagnosed a collapsed Dynamic Fuel Management (DFM) hydraulic lifter in Cylinder 3. The lifter bank was replaced under the factory powertrain warranty. Incident 2 (Approx. 77,000 miles): While driving at high speed on the interstate, the exact same vehicle behavior occurred. The engine suffered a sudden, total loss of power, and all dashboard warning lights illuminated simultaneously. Out of absolute necessity and to avoid a catastrophic high-speed collision on a dangerous stretch of highway, the severely crippled vehicle had to be forced through active interstate traffic without proper engine power all the way to my home. The vehicle has since been inspected by a GMC dealership, which has confirmed that the exact same Cylinder 3 lifter has failed a second time. The dealership and the GMC Regional Service Manager are currently refusing to honor the 24-month dealer-installed service parts warranty, demanding an out-of-pocket deposit of $5,000, and denying alternative transportation. GM's failure to permanently remediate this known, systemic valvetrain defect has twice left me navigating a failing vehicle through high-speed highway traffic, heavily compounding the safety risk.

ENGINE, POWER TRAIN
Vehicle started showing a po308 code. Called sewell gmc In midland where I purchased the vehical they were 2 months out on diagnostic services. So I took it to another shop. They ran a camera into the problem cylinder and for scaring on the walls. They said it was due to the afm system and the engine was unrepairable. So now I am out 17,000 dollars and stranded over 700 miles from my home due to a manufactured defect.

Lifter/camshaft/engine failure. GM knows this is an issue with these models/years. They only want to cover half of the repair sticking me with a bill for $5600. Safety is a concern because they know this is an issue and not issuing a recall currently. I waS driving when this happened which could have caused me to get into an accident. Very dangerous. Car is currently as GMC Started by showing low oil in between oil changes last year. Went in for an oil change and told them about it. Dealership told me it was the air hose box and that they didn't see any other issue. I believe they are told to lie to get each customer further out of warranty. I was driving and all of a sudden the car started violently shaking and lights started flashing at me.

Driving on the freeway the engine started making super loud knocking noises for while going 70mph . Then it immediately died everything turned off no power I was barely able to get it off the freeway while coasting. And my husband tried to push it off the road more but when it dies we are not able to put the car in neutral !! It’s a push button gear shift ! When there’s no power the buttons don’t work!! It was 105 degrees out that day in Sacramento , the car had zero power the battery is not the problem . The motor is blown and the car hasn’t started since that day. These cars are dangerous to just die in the middle of the freeway! The motor has already been replaced in Feb 2026, we bought it in march of 2026 with 57k miles on it. I added about 12k miles and the motor blew up again!

My 2021 GMC Yukon Denali features the 6.2L L87 V8 engine. This vehicle was previously serviced for the GM voluntary recall regarding engine bearing failures, and the dealership completed the remedy by inspecting the motor and changing the oil to the thicker 0W-40 specification. Since completing this recall fix, the vehicle has developed an intermittent rough idle and sputtering behavior. The dealership has been unable to duplicate the intermittent issue and claims it falls under normal behavior. I am filing this report because my vehicle is exhibiting post-recall remedy engine degradation, matching the exact failure patterns outlined in the NHTSA Engineering Analysis EA26005 escalated on August 20, 2026. This intermittent sputter represents a severe safety hazard regarding potential sudden loss of motive power while driving.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, BACK OVER PREVENTION: WARNINGS
On August 17th, 2026 while approaching a nature preserve entrance at approximately 1 mph, my 2023 GMC Yukon Denali Ultimate suddenly accelerated on its own, without the driver pressing the accelerator pedal, striking a split-rail fence and a tree. Airbags did not deploy. The front collision system didn't issue any alerts about the fence and tree. A GM software update had been installed a couple of days before this incident . In the weeks prior, the vehicle had also intermittently failed to hold side mirror position and periodically failed to deploy the power running boards. I request that GM and NHTSA investigate a possible link between the recent software update and an unintended acceleration event, potentially related to the adaptive cruise control or another driver-assist/body control module.

The contact owns a 2017 GMC Yukon XL. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 19V645000 (Service Brakes, Hydraulic); however, the failure occurred after the recall repair. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed and went to the floorboard. No warning light was illuminated. The vehicle continued to move forward and rear-ended the vehicle ahead. There was no air bag deployed. There were no injuries sustained. A Police report was not filed. The contact stated that there was damage to the front bumper. The vehicle was driven away from the crash scene. The vehicle was taken back to the dealer, and the failure was associated with the recall. The contact stated that an unknown module needed to be replaced, but the manufacturer had to authorize the repair. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 170,000.

Engine blew at 8,762 miles in the middle of the night with 3 small kids in the car. Currently 41 days waiting for a new engine. We were driving and it started making a clapping sound like something was caught underneath. We had to drive a could miles to find a safe place to pull over. If we increased speed, the clapping increased and it slowed when we slowed. Hauled it to the local dealership and they said it was the engine. The dealership it was purchased at says the same thing. There was no warning. After a couple of miles of the clicking/clamping sound, the car started to shake and then died. There were no warnings or light on the dash of any signs of distress until it died. It was a couple of miles before we even had a safe place to pull over on the side of the highway. Going 70mph on a highway that is posted to be 70mph with 3 kids in the car, in the middle of the night, put my family’s life in danger along with other cars behind us. Clearly safety and quality isn’t GM’s top priority. This is our 5th Yukon. Our 13th General Motors vehicle. To say we are disappointed is an understatement when we have been devoted to GM for over a decade.

POWER TRAIN
2022 GMC Yukon XL suffered catastrophic transmission failure at approximately 87,000 miles. An ASE-certified transmission repair facility determined that the torque converter failed, resulting in transmission damage requiring over $7,000 in repairs. GM declined any assistance solely because the repair was performed by an independent ASE-certified facility. I am concerned that a major transmission component failure at this mileage may represent a broader defect, particularly given transmission-related service bulletins and NHTSA Recall 26V085 affecting certain 2022 Yukon XL vehicles.
